IMPROVEMENT IN KEROSENE OlL BURNERS.

Specification forming part of Letters Patent No. 48,450, dated June 27', 1865.

To all whom it may concern:

Be it known that we, HUGH SANes'rEe and JAMES SANGSTER, of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvementsin Kerosene-Oil Burners; and we do hereby declare that the following is a full and exact description thereof, reference being bad to the accomence marked thereon.

The nature of our invention consists in constructing a burner with a spring at its base, so made that the burner may be connected to the collar by pressing it down into it and then turning it partly around.

To enable others skilled in the art to make and use our invention, we will proceed to describe its construction and operation.

We construct our burners of brass, as being the most suitable material.

Figure 1 represents a side elevation of the burnercomplete, with the collar and insidecase or tube, A, connected thereto, also the case forming-the lower part of the burner, to which the spring is attached. Fig. 3 is a view of the bottom of the burner, showing the wick-tube The upper part of the burner is made in the usual way, and need not be described here.

In Fig. 1, B is thecollar, A the case or tube, attached to and forming a part of the collar. The dotted lines 0 and 0 represent the lower part of the burner, to which is attached the spring. D is the wick-tube, E the spring.

The dotted linesG show the shapeoli the spring.

insidevot' the case 0 G, and F is the point where it is fastened.

In Fig. 3, I is a bottom view of the spring E. The burner is fastened to the'collar by pressing it down into it and then. turning it until the spring-E passes by the corners J or J and into the notch K at the bottom of the collar, when it springs out over the bottom of said collar and holds it firmly in its place. It is released by turning it back past the notch or point J, which forces the spring in, thus allowing the burner to be lifted out of the collar.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. Constructing the spring E so that it connects the burner to the collar B by pressing it down into said collar and turning it around until it springs over'either corner J or J into the notch K, thus bringing the spring under the lower edge of the collar.

2. In so constructing the lower part, A, of the collar B that when the burner is turned so that the spring passes the corner J it is forced into the case A and allows the burner to be drawn out easily.
